Abstract

A vision correction apparatus and system for correcting various forms of strabismus. The apparatus has a viewing mechanism for viewing images, a dynamic stimulus device to be engaged or disengaged depending on control signals generated from the apparatus, a measuring mechanism for observing and measuring viewing activity of the user, data storage mechanism for storing data measured by the measuring mechanism; and control mechanism for assessing stored data and, in relation to an assessment made of the stored data, for generating and transmitting a control signal to engage or disengage the dynamic stimulus device. The measuring mechanism further measures alpha, beta, and theta brain waves after viewing a structured and an unstructured image for a pre-determined period of time, observes and measures electrooculogram (EOG) patterns of each eye, and observes and measures interfering muscular movement but use of an electromyogram (EMG) after which the data obtained from the measurements is assessed by the control mechanism to establish individualized normalizing co-efficients and values, to establish brain visual activation function and value, to establish absolute differences between EOG patterns of the eyes, to account for interfering muscular movement not associated with EOG patterns, and to establish a trend which, if supportive of vision correction, engages the dynamic stimulus device and, if not supportive of vision correction, disengages the dynamic stimulus device thereby encouraging a user to self-correct by repeating activity which engages the dynamic stimulus device.
